Flexible Installation Options:
The UPS is designed for versatile deployment. It can be rack-mounted in a standard 19” server cabinet using the included mounting ears or a user-supplied rail kit. For standalone use, dedicated vertical brackets are available, enabling installation outside of the rack environment. When paired with multiple external battery modules in a vertical configuration, optional stand extensions can be added to enhance stability and maintain proper alignment of all components.
